PV Power for Urban Water Supply

This work describes the application of a solar photovoltaic (PV) system in the urban water sector, especially related to water pumping. The Sun and gravity are two basic natural and renewable sources of energy. It is pure natural energy that has no harmful effects on the environment, spread everywhere and available for use. Solar photovoltaic systems can be successfully applied in many areas in water sector and especially in water supply. Due to the importance of water supply for urban area sustainability, and due to a significant energy consumer whose price is increasing each day, alternative solutions to power systems are sought in the form of water supply systems, such as a PV generator. It is a complex system, whose functioning is defined by a whole range of factors: climate, soil, hydrological, water consumption in the cities etc. It can be optimized only with the application of a systematic approach and the use of adequate tools. The paper will show that the solar photovoltaic systems are efficient in use in urban water sector.
